ArrAn'a'ms FOR TINTING MOTION PICTURE FILMS AND THE LIKE Applicationfiled December 1a. 1929. Serial No. 414,938.

The main objects of this invention are: 7 First, to provide a machine orapparatus for tinting motion-picture films and the like whereby onelongitudinal section or portion of the film may be tinted with one colorand another longitudinal section with another color. e

v Second, to provide an apparatus forthe tinting of films whichisautomatic in operation and fof very large capacity; Y

"Object's pertaining't'o details and economies of'my invention willdefinitely appear from the description to follow. 'The inventionisdefined in the claims I A structure embodying the features of myinvention clearly illustrated in the accompanying drawings, in which: I

- F'g. 1 is an end elevation with parts brok en away to better disclosethe structure.

Fig, 2 is a fragmentary plan view.-

Fig. 3 is a fragmentary viewmainly in vertical section on line 3-3 ofFig. 2. n Fig. 4 is a conve'ntionalized perspective view illustratingthe film supportingpulleys.

Fig.5 isafragmentary view of the film of which both-the longitudinalforeground and background sections are indicated as colored or tin-ted.1 {Ifhave illustrated my'improvements in a machine especially'designedfor thetinting of 'films such as are illustrated in my appli cationforLetters Patent Serial No. 393,368, filed September 18,1929, inwhichthe film comprises a series of background pictures and a series of imagepictures disposed trans versely of the film in coa'cting or associatedpairs/.7" '1 Theyframe 1 is ofsu-itable character to sup.-

portthe parts and is provided with a bed or top v2. .The dye or colortank 3 is removably supported on the top 2. A frame or support 4 fortheimmersing pulleys .5 is pivotally 'mounted on'the brackets, 6 bymeans of the 4f? pivot rod 7. The spindles 8 of'the immersing pulleysare mounted on the swinging end of the frame and supported at an anglepreferably in an inclined relation to the surface of 1 the coloringliquid indicated at 9 in Fig. 3. .9 The frame carrying these immersingpulleys may be raised from or lowered into the tank by means of thescrews 10 swivelled in the cross piece 11 on the brackets and havingthreaded engagement with a cross piece 12 on the frame. The cross pieces11 and 12 '53 are journaled or pivoted for rocking movement on thebrackets and frame respectively to permit theswinging of the frame.

The rests 13 are threaded into the cross piece 14 on the outer end ofthe support 4 to coact with the bottom of the tank. Lock nuts 15 areprovided for holding these rests in adjusted position. These restssupport the immersing pulleys in accurate relation to the surface of thecoloring liquid.

The immersing rollers are provided with peripheral ribs 16 at each endhaving sprockct teeth 17 adapted to engage the feed perforations of thefilm.

' 'The supply spindle 18 for the film indicatedat 19 is mounted on anarm 20 on the immersing roller support. A supporting disk 21 is providedin coacting relation with the spindle. A friction brake or dragdesignated generally by the numeral 24 is provided for the supply orwork spindle. The details of this are not illustrated. V

The tank 3 is provided with an overflow 25 delivering to the supplyreservoir 26, the liquid level'being maintained in the tank 3 by meansof a pump 27. The plunger of the pump is indicated at 28 and driven fromthe crank disk 29 on the shaft 30. The pump is connected to deliver tothe tank 3 by the conduit 31.

, Thefilm driving-sprocket 32 is disposed in advance of-the windingspindle 33 which has a friction driving means. I

Between the driving sprocket and the im mersing pulleys I provide aplurality of guide pulleys 34, 35 and 36 which support the film topermit its drying before it is wound. These dryin reaches are ofsuitable length P to permit this.

In the embodiment illustrated the motor 37 is mounted on the frame 1.reduction unit designated by the numeral 38 is provided in order thatthe film may be driven at the desired speed. The speed is furtherreduced by the driving connections which comprise and is provided theshaft 39 disposed longitudinally of the machine and connected to theunit 3 8 by means of the sprocket chain 40 and the sprocket wheels 41and 42. A. ack shaft 43 is connected to the shaft 39 by means of thesprocket chain 44 and the sprockets 45 and46. The jack shaft 43 is inturn connected to the driving sprocket spindle 47 by means of thesprocket chain 48 and the sprockets 49 and 50. The supporting rollers 51are carried by the usual spring-tensioned arm 52.

The winding spindle 33 isconnected to the jack shaft 43 through thefriction disks 54 55. A guide arm 56 is also provided carried by-thesupport 57 -With the parts thus arranged the film isposed in pairedtransverse relation on the coloring of a longitudinal section of filmand film. The pairs of pictures are indicated at '58 and 59 on the filmillustrated.

The finishedfilm is conventionally'illustrated in Fig. 5 with bothforeground and background portions in colors. It Will'be understood thateither may betinted or colored.

My improved apparatus permits the rapid this may be done with veryuniform results and with little attention on the part of the operator. v

@Having thus described my invention what I claim as new and desire tosecure by Letters Patent is: v v 1.
